Patent AU-659622-B2 (AU)
Title: Efficient microcapsule preparation and method of use
Inventor: WALLACE SIDNEY
IPC: B01J13/20
Filed: 1991-10-02
Granted: 1995-05-25
Abstract: The present invention relates to a method of preparing microcapsules suitable for encapsulation of therapeutic and diagnostic agents. The capsular coats are prepared from biodegradable polymers. In a particular aspect of the invention, surface charge of the polymeric material is altered by conjugation of an amino acid ester to the polymer, providing targeting to specific tissue cells. Encapsulation of hydrophilic radiodiagnostic agents in 1  mu m capsules provides improved opacification. Encapsulation of cytotoxic agents in 100  mu m capsules is useful in chemoembolization procedures.

Title: Radar system transmits information to target - uses same antenna and transmitter without affecting doppler evacuation
IPC: G01S13/86
Filed: 1968-11-29
Abstract: The pulse Doppler radar system not only acts as a standard radar system but also allows information to be transmitted to the target using the same antenna and the same transmitter without affecting Doppler signal evaluation. The information is transmitted by a PCM or pulse phase modulation. The information is made into a pulse telegram and modulated onto a carrier whose frequency at any instant is given by the sum of the radar pulse carrier frequency, the Doppler frequency of the target and a figure equal to half an odd integral multiple of the repetition frequency of the radar pulses.

Title: Anti-dive front wheel suspension - with split braking effort to balance braking reaction on damper
IPC: B60G21/055
Filed: 1969-04-21
Abstract: The brakes on the front wheel are divided into asymmetric blocks (3, 5) set to straddle the hub. The reaction force from the brakes is arranged so that two moments are set horizontally onto the body while the remaining reaction force has two other components; one directed vertically down onto the wheel and one upwards into the body. The trailing edge of the brake support frame (1) is linked to the car body by an angled strut (8) so that some of the brake reaction force presses upwards onto the body to compensate the brake dive effect.

Abstract: The corrosion damage, particularly that due to local pitting, which occurs on hard-drawn copper tubes used in the sanitary sector is generally caused by carbon-containing films but also by oxide films. A carbon film on the inside of the tube is formed, for example, if the drawing compound added when drawing the tube is subjected to excessive heat. To avoid these damaging films and to improve the pitting resistance of hard tubes made of copper or copper-based alloys, the tubes are first of all degreased. In a further process step, the inner surface of the tubes is then treated with a blasting abrasive in order to establish a minimum roughness. A mean roughness of 0.8 to 1.0  mu m has proven particularly advantageous. The hard-drawn tubes treated by the method according to the invention have none of the films which promote pitting, even after brazing and/or hot bending.
